BMC Air Filter - Reviews

Cheapest way to upgrade the power of your engine there are 2 versions of this filter - the race filter and the regular filter. The race version is designated by a stripe running down the length of the filter. Both are rechargeable. I have the race one in my 05 R1 after finally dirtying up my stock oil and paper filter I bought the race version and the difference was immediate. The bike breathed a lot better and the power was very noticeable and I'm not sure if it's just me but my engine growls at you. Well worth the money here. Before you buy pipes Power Commanders and mufflers try this first.
